WebMar 19, 2024 · To implement the DFS we use stack and array data structure. There are two cases in the algorithm: Whenever we visit a vertex we mark it visited and push its adjacent non-visited vertices into the stack and pop the current vertex from the stack. If all the adjacent vertices are visited then only pop the current vertex from the stack. WebMar 26, 2024 · It relies on recursion and I assure you, that for large enough connected graphs with it will blow the stack resulting in UB. Proper DFS/BFS implementation store states-to-be-visited in a std::stack or std::queue or something similar while the visit routine occurs in a single loop instead of recursion.

WebFeb 9, 2014 · Using the Code. The logic of the algorithm is traverse to left subtrees as much as possible and push them into the stack. When reaching the end, you pop one element from the stack and print it.Then for the node that is popped from the stack again, we should do the same thing (find the left elements) on the right subtree of that node, and we ...
